Modernizing healthcare software from desktop to web

At Inmed / LOGEX, I helped move healthcare workflows from legacy desktop software to modular web applications. I worked across Java/Spring APIs, PostgreSQL data models, Vue and React interfaces, and access controls.

Enterprise delivery

Application development at Inmed / LOGEX, covering web workflows, backend services, reporting, and authentication.

Project at a glance

The need: Healthcare teams needed established desktop workflows to become maintainable web applications for data handling and reporting.
What I delivered: Modular web workflows connecting uploads, processing, and reports, backed by Java/Spring APIs, PostgreSQL, and explicit access controls.

Work completed at Inmed / LOGEX. Patient records, customer screens, and internal systems remain confidential.

My contribution

Reworked healthcare desktop workflows into modular web applications across the interface, service, and data layers.
Built REST APIs, PostgreSQL data models, and dashboards for uploads, data processing, and reporting.
Implemented two-factor authentication, role-based access, and internationalization as part of the application workflows.
Supported maintainability with JUnit/Mockito tests and technical documentation alongside the implementation.

Technical challenge

Modernizing a desktop workflow involves more than rebuilding its screens. Uploads, validation, processing, and reporting need to work together in a web application, with access rules and responsibilities made explicit across the stack.

My approach

I developed Vue and React interfaces backed by Java/Spring REST APIs and PostgreSQL. The work included data models and reporting dashboards, two-factor authentication, role-based access, internationalization, and JUnit/Mockito tests.

Engineering decisions

Separate interfaces, services, and data

I built modular web workflows around REST APIs and PostgreSQL models. Clear responsibilities make it easier to extend a workflow or test its processing logic without coupling every change to the interface.

Build access controls into the application

I implemented two-factor authentication and role-based access alongside the workflows they protect. JUnit/Mockito tests and documentation support the team maintaining those applications.

Explore the system architecture

Vue and React interfaces connect to Java/Spring services for processing and access checks, backed by PostgreSQL records and reporting queries. Internal customer topology is omitted.
